Storage Spaces offer a new way to manage storage space on a Windows system. It makes it very easy to add disk space to a Windows system. Using Storage Spaces, we can take all of the storage devices in the system and pool all the available space on those devices together. This is very useful because if we run into a situation where we're running out of disk space, all we have to do is add an additional disk to the system and then add its free space to the storage pool. Then, Windows automatically adds the new free space from the new device to our existing storage.We don't have to keep track of what data is stored on which drive. We also don't have to worry about resizing volumes. All the space is added, and you see one big drive where you can store your information. Storage Spaces Components 1:23-2:52 Now, if you've ever worked with Linux systems and used Logical Volume Manager to manage storage space on Linux, then the concepts we're going to talk about here are going to be quite familiar to you.Storage Spaces on Windows is composed of three key components. First, we have our storage devices represented by these three different hard drives over here. We can use storage space from a variety of different storage devices. It doesn't matter if they're SATA drivesor external hard drives. You can use whatever storage devices that you have on your system, and they don't all have to be the same type. We take all of the available storage space on these various devices, and we pool them together into a storage pool. The pool is a logical concept. It's not a physical device. It's a logical concept that is composed of all the free space available on these storage devices that we specify. Now, we can take this pool of available storage space and define individual storage spaces as identified by these volumes down here. We can take the pool and create one storage space out of it, or we can define multiple storage spaces, each drawing space from the same storage pool. The key thing to remember is that as far as the Windows operating system itself is concerned and the end user for that matter, these just look like disk drives in the system, logical disks. So this could be the E drive and this could be the F drive. We'd have two logical drives defined that are really storage spaces, but they're composed of space from three separate hard disk drives. The space from these drives is pooled together and then allocated to a specific storage space. Benefits of Storage Spaces 2:53-3:25 Now, using storage spaces over traditional storage options has a lot of benefits. The key among these is the fact that if you start to run out of free space in any given storage space that you've defined, all you have to do is go out and buy a new storage device like a new SATA hard disk drive, install it in the system, add the free space on that new device to your existing pool, and then allocate that new space to one of your existing storage spaces. And that's it, the space is available. You don't have to repartition anything. You don't have to resize any volumes. You don't have to

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
